In my opinion this whole weapon foraging in MP is bad, outdated system.
Players should get to select their weapons at spawn. (The only weapons
laying around in the maps should be those left behind by the dead)
I think best system might one where before you spawn into the MP game
you would get this "available items screen" where you can choose what
ever weapons, ammo and gadgets you want to take...
You could have like: 5 Pulse rifles, 3 Flamers, 1 Smartgun, 10 Pulse rifle
clips, 8 Pulse rifle nades, ... (Lot more stuff than you can actually take)
But what ever you take is then gone from your inventory for some time.
And different items would have different replacement times... One pulse
rifle every 10 minutes, one Flamer every 15 min, one smartgun every 30
min, ... one pulse rifle clip every min, one pulse rifle nade every 10 min...
If you take huge loads of the most powerfull toys with you and die again
and again and spam your nades then your left with nothing but garbage
for while...
